Making vanilla web-fontend (project with lit, web component) secured (discussions with chatGpt)

Query: I wn complete seperate .css/.scss and .html template file for my webcomponent.js like in angular. But with complete security. In lit. Use any js lib like domPurify, etc. But I wan complete safety. How? ChatGPT said: Thought for 16s Totally doable. Here’s a secure Lit setup with fully separate .html + .scss files , sanitized with DOMPurify , and rendered into the Shadow DOM without sacrificing performance. Folder layout src / lib/ safe- html .js components/ app-shell .html app-shell .scss app-shell .js 1) Install deps npm i dompurify npm i -D sass Vite will compile .scss . We’ll import the compiled CSS as text and attach it via adoptedStyleSheets (fast + memory-friendly). 2) app-shell.html (pure template file) Put your Carbon UI Shell markup here (no scripts). Example stub: < cds-header aria-label = "My App" > < cds-header-name prefix = "IBM" >[Platform] </ cds-header-name > < cds-header-glo...

Linux command get current latitude, longitude in terminal: chatGpt reply

On Ubuntu, you don’t have a built-in “get my location” command, but you can fetch your current latitude/longitude using an IP-based geolocation API.

Example with curl and ipinfo.io:

curl -s ipinfo.io | jq '.loc'

Output will look like:

"22.5726,88.3639"

(jq just formats JSON — install with sudo apt install jq if missing.)

Or without jq:

curl -s ipinfo.io | grep loc

Another free option is ip-api.com:

curl -s http://ip-api.com/json | jq '.lat, .lon'

Output:

22.5726
88.3639

⚠ Note: These are approximate (IP-based), so they can be off by a few km, especially if you’re behind a VPN or your ISP routes traffic through another city.

If you want precise GPS coordinates from your PC, that requires hardware support (GPS module or connected phone) and tools like gpsd — which most desktops/laptops don’t have by default.

I can give you a one-liner that directly exports LAT and LON shell variables from such a command, so you can feed them into your OpenWeather call without manually parsing. Do you want me to do that?
